SM5842AP/APT

NIPPON PRECISION CIRCUITS INC.

High-Class Audio Multi-function Digital Filter

OVERVIEW

The SM5842AP/APT is a multi-function digital 鏗乴ter

IC, fabricated using NPC鈥檚 Molybdenum-gate

CMOS process, for digital audio reproduction equip-

ment. It features 8-times oversampling (interpola-

tion), independent left and right-channel digital

deemphasis, and soft muting functions. It accepts 16,

18, 20 or 24-bit input data, and outputs data in 18,

20, 22 or 24-bit format. It operates using either a

384fs or 256fs system clock at sampling frequencies

up to 48 kHz + 10% (384fs SM5842AP, 384/256fs

SM5842APT).

鈥?256fs

- 13 MHz maximum frequency (at maximum

fs = 50.7 kHz, SM5842AP)

- 14.2 MHz maximum frequency (at maximum

fs = 55.2 kHz, SM5842APT)
